Measurement
Once you have completed all preparations
, you can start with
the actual measurement.
1) Connect the desired sensor to the meter. Some sensors
require a special preparation. Information on this can be
found in the sensor’s user manual.
2) Switch the meter on using the
on/off
or
meas
key.
3) Depending on the measurement method and the sensor
used, immerse the sensing part of the sensor in the medium
to be measured.
4) Watch the display and wait for the reading to stabilize.
5) By pressing the
STO
key, you can hold and save a measured
value (see data logger, page 39).
Measurement can also be controlled using the Paraly SW 112
PC software.
Toggling the Measurement Display
During measurement, you can toggle the measurement dis-
play by pressing

:
• pH: between pH and ORP values in mV
(also with pH/ORP combo sensor)
• Cond: between compensated and uncompensated mea-
sured value (when temperature compensation, SAL or TDS
are activated)
• Oxy: not applicable
